LONDON, March 15 (Reuters) - Gold ditched its safe-haven mantle and slid by more than 1 percent on Tuesday, caught in a broad-based sell-off by commodity investors who grew increasingly unnerved by Japan's growing nuclear crisis.
Other safe-haven assets such as U.S. Treasuries or the Swiss franc <CHF=> rallied after Japenese stocks posted their worst two-day slide since 1987 and the country faced potential disaster after a nuclear power plant north of Tokyo exploded.
The VDAX-New volatility index <.V1XI>, which reflects German options volatility, rocketed to its highest since late August 2010, while crude oil and the other precious metals tumbled.
Gold <XAU=> was down 1.2 percent at $1,409.05 an ounce by 0953 GMT, after having risen by as much as 1 percent on Monday. U.S. gold futures <GCv1> fell 1.1 percent to $1,409.10.
"Gold has gone down less than other commodities, perhaps sometimes it just maybe is the proportional response which is the important thing," said Mitsubishi analyst Matthew Turner.
"Gold has not been acting as much as a safe haven as other safe-havens but it's also not been acting as much as a commodity as other commodities."
Analysts said earlier part of the pressure on gold stemmed from investors cashing in on the metal's 8 percent rise in the last month on the back of escalating violence in the Middle East to cover losses or margin calls on their equity holdings.
"We argue that it's not unusual for gold to tumble during initial episodes of a severe broad asset sell-off. Investors sometimes have little choice but to sell the yellow metal to cover margin calls and losses elsewhere before gold then divorces itself from the downtrend," said UBS strategist Edel Tully in a note.
"In the current climate there is more opportunity for gold to rally, as the need for safe havens accelerates," she said.
ECONOMIC IMPACT
Japan, the world's third largest economy, faces a recovery and reconstruction bill of at least $180 billion -- 3 percent of its annual economic output -- or more than 50 percent higher than the total cost of the 1995 earthquake in Kobe. [
]The yen rallied against higher yielding currencies on Tuesday, driven by expectations that Japanese insurers and other companies will need to repatriate funds to help pay claims and reconstruction costs of the country's worst earthquake. [

Yen-priced gold <XAUJPY=R>, which rallied to its highest since at least 1983 last week, fell by 1.4 percent, set for its biggest one-day decline since late January.
"It still looks like it's constructive. It's just consolidating. But if we get a large sell-off in equities, people will tend to sell gold," said Jonathan Barratt, managing director of Commodity Broking Services in Melbourne.
"But if it's a major concern, then people will eventually go to gold as the last resort."
Rising tensions in North Africa and the Middle East, where Libyan rebels continue to battle troops loyal to Muammar Gaddafi for control of key oil ports, pushed gold to a record $1,444.40 an ounce last week.
Brent crude oil futures fell by as much as 2.2 percent <LCOc1> as Japan's deepening nuclear crisis fed risk aversion, while copper <CMCU3> shed more than 1 percent and several agricultural commodities also came under pressure. [
] [ ] [ ] [ ]Platinum prices <XPT=> shed nearly 2 percent, falling to their lowest in two months, after major Japanese car makers including Toyota <7203.T>, Nissan <7201.T> and Honda <7267.T> stopped vehicle production following Friday's earthquake that has crippled roads, railways and ports.
According to refiner Johnson Matthey, Japan was the largest single national user of platinum in 2010, and accounted for 18 percent of global autocatalyst demand of 2.985 million ounces. Palladium <XPD=> fell by 2.3 percent to $732.00 an ounce, having fallen for five days in a row, its worst streak since early August last year.
Silver <XAG=>, often bought as a cheaper, but more volatile safe-haven alternative to gold, fell by 3 percent to $34.83 an ounce.
